Here's a general outline of the process, but this is NOT a substitute for a professional repair manual:
1. Safety First:
* Disconnect the battery: This prevents accidental sparks.
* Ventilation: Work in a well-ventilated area. Gasoline fumes are highly flammable and potentially lethal.
* Eye protection and gloves: Protect yourself from fuel spills and other hazards.
* Fire extinguisher: Have a readily available fire extinguisher rated for flammable liquids.
* Jack stands: Never work under a vehicle supported only by a jack. Use jack stands for safety.
2. Preparation:
* Locate the fuel tank: It's usually located under the vehicle, toward the rear.
* Identify fuel lines and electrical connections: You'll need to disconnect these.
* Gather tools: You'll likely need various wrenches, sockets, screwdrivers, fuel line disconnect tools, and potentially a fuel pump removal tool.
3. Fuel Removal:
* Drain the fuel tank: This is crucial to minimize the risk of spills. Use a siphon pump or drain valve to carefully remove the fuel. Dispose of the fuel properly according to local regulations.
4. Disconnecting Components:
* Fuel lines: Carefully disconnect the fuel lines using the appropriate tools. You might need to relieve pressure in the fuel system before disconnecting.
* Electrical connections: Disconnect any electrical connectors to the fuel pump and sending unit.
* Fuel tank straps: Locate and loosen the bolts or straps securing the fuel tank to the vehicle's frame. These are often difficult to access.
* Exhaust system: Depending on the specific location of the tank and exhaust components, you may need to loosen or remove parts of the exhaust system to gain access.
5. Lowering the Fuel Tank:
* Slowly lower the tank: Carefully support the tank as you loosen the straps. You might need a helper to assist in this step.
* Support the tank: Use jack stands or other suitable supports to prevent the tank from dropping unexpectedly.
6. Removal:
* Clear the path: Ensure there's enough space to safely maneuver the fuel tank clear of the vehicle.
Important Considerations:
* Vehicle-specific differences: The exact location and mounting of the fuel tank, as well as the access points, will vary slightly depending on the specific trim level and options of your 2001 Yukon XL.
* Professional help: If you're not comfortable performing this task yourself, it's best to have a qualified mechanic do it. Working with fuel is dangerous, and improper handling can lead to serious injury or damage.
Again, refer to a repair manual for your specific vehicle before attempting this task. This outline provides only a general overview and may not cover all aspects of the process. Safety is paramount.
